dynamic router in navigation menu

[zerefgg]

Hello,
how can I make a router with a dynamic link, I didn't find any hook about it.
e.g : example.com/user/USERNAME/custompagehere

I want USERNAME to change for each connected user that clicks on the navigation menu link

https://example.com/me/xxxxxx will redirect a user to https://example.com/user/[username]/xxxxxx

Try it out: /me/bookmarks
